Lanced ruffled turbulizer

Abstract

A heat exchanger combines a lanced fin surface with a ruffled fin surface to create a lanced ruffled turbulizer. The lanced ruffled turbulizer combines the turbulence generated by lancing the heat transfer or turbulizer surface to the deflection forces on the fluid stream generated by a ruffled turbulizer to improve the thermal performance of the heat exchanger.

What is claimed is: 
     
       1. A turbulizer comprising: a plurality of connecting interposing lines of fin forming a corrugated pattern and generated from a flat sheet of metal, said plurality of connecting interposing lines of fin defining a repeating corrugated pattern including, a first section approximately parallel to a horizontal and situated in a horizontal plane,   a section approximately parallel to said horizontal and lying in said horizontal plane,   a third section sloping downward at a first angle from a first top corner of said second section toward a first bottom corner of a successive occurrence of said first section, and   a fourth section sloping upward at a second angle from a second bottom corner of said first section toward a second top corner of said second section.     
     
     
       2. A turbulizer as claimed in claim 1 wherein said first angle and said second angle are substantially equal. 
     
     
       3. A turbulizer as claimed in claim 1 wherein said repeating corrugated pattern defines a lanced ruffled fin surface. 
     
     
       4. A turbulizer as claimed in claim 1 wherein said third and fourth sections are partially offset from said first section. 
     
     
       5. A turbulizer as claimed in claim 1 wherein said third and forth sections are partially offset from said second section. 
     
     
       6. A turbulizer comprising: a plurality of connecting interposing lines of fin having a surface, and   means for simultaneously lancing and ruffling said plurality of connecting interposing lines of fin to define a repeating corrugated pattern.   
     
     
       7. A turbulizer as claimed in claim 6 wherein said means for simultaneously lancing and ruffling said fin surface comprises tooling. 
     
     
       8. A turbulizer as claimed in claim 6 wherein said repeating corrugated pattern comprises a lanced ruffled fin surface. 
     
     
       9. A method for creating a turbulizer comprising the steps of: generating a continuous length of fin from a flat sheet of metal, said fin having a surface and further having a plurality of connecting interposing lines of fin; and   defining a repeating corrugated pattern on said surface including, a first section approximately parallel to a horizontal and situated in a horizontal plane,   a second section approximately parallel to said horizontal and lying in said horizontal plane,   a third section sloping downward at a first angle from a top corner of said second section toward a bottom corner of said first section, and   a fourth section sloping upward at a second angle from said bottom corner of said first section toward a top corner of said second section.     
     
     
       10. A method as claimed in claim 9 wherein said first angle and said second angle are substantially equal. 
     
     
       11. A method as claimed in claim 9 wherein said repeating corrugated pattern defines a lanced ruffled fin surface. 
     
     
       12. A method as claimed in claim 9 wherein said third and fourth sections are partially offset from said first section. 
     
     
       13. A method as claimed in claim 9 wherein said third and fourth sections are partially offset from said second section. 
     
     
       14. A method for creating a turbulizer comprising the steps of: generating a plurality of connecting interposing lines of fin having a surface, a nd   simultaneously lancing and ruffling said plurality of connecting interposing lines of fin to define a repeating corrugated pattern by, forming a first section approximately parallel to a horizontal and situated in a horizontal plane;   forming a second section approximately parallel to said horizontal and lying in said horizontal plane;   forming a third section sloping downward at a first angle from a first top corner of said second section toward a first bottom corner of said first section; and   forming a fourth section sloping upward at a second angle from a second bottom corner of said first section toward a second top corner of said second section.
